Five Things That Surprise Foreign Buyers in Japan
Five Things That Surprise Foreign Buyers in Japan
Most of the Japanese property process is familiar — find a place, sign a contract, pay, register. Five details routinely catch foreign buyers off guard.
1. Cash offers dominate
Roughly 40% of residential transactions are all-cash, including most akiya, many investment units, and a meaningful share of central-Tokyo deals. Sellers are genuinely indifferent to financing in a way that surprises buyers from mortgage-default markets. If you're competing on a hot listing, cash closes 2–3 weeks faster than a mortgage.
2. Setback (セットバック) can shrink your land
If a property fronts a road narrower than 4 meters, the Building Standards Act requires you to set the building line back to create a future 4m width. The strip becomes effectively unusable land that you still own and pay tax on. Ask for the setback area in m² before bidding — it can quietly remove 5–15% of usable footprint.
3. No road frontage, no rebuild
Article 43 of the Building Standards Act requires at least 2 meters of frontage on a designated road to legally rebuild. Older properties on private alleys or down narrow stair-passages often fail this test. They can be bought, lived in, even renovated — but cannot be torn down and reconstructed. Listings that are unusually cheap for their location are often hiding this.
4. Renovation may need permission
Major structural changes — moving load-bearing walls, expanding footprint, changing roof — require building permits. Mansion units have additional 管理規約 (HOA bylaws) that can prohibit floor-material changes, water-supply rerouting, or window modifications. Cosmetic refresh is usually free; anything structural is not.
5. The 重要事項説明 takes hours
Before signing the purchase contract, the buyer's licensed agent reads aloud a 重要事項説明書 (statement of important matters) covering zoning, easements, restrictive covenants, building law status, water rights, and known defects. It is legally required and typically takes 60–90 minutes. Foreign buyers expecting a quick title-company-style closing are often unprepared. Read the document in advance and bring a translator if your Japanese isn't legal-grade.
None of these are dealbreakers, but each one routinely turns up at signing instead of inspection. Catching them early is cheaper than catching them late.
